Re: HFS-4 Q&A, application for your engine...
It looks like a very nice bolt on.
Your questions:
1. You can use the hydra's spare PWM output to drive the HFS-4 direct and create your own map or HFS-4 tracks the existing fuel flow and MAP sensor (if available within Hydra).
2. The system is a trunk-mount system. Electronically, it is very straight forward other than the Hydra interface (two wires), just connect the usual 12V and ground supply. All other harnesses are plug and play.
3. I can arrange to have kit to be shipped from the USA because our postal service does not have a tracking system.
